Antimutagenic and Antiproliferative Activity of the L. Extract Loaded in Nanofibers of Gelatin/Agave Fructans Elaborated by Electrospinning.

Background: The Coccoloba uvifera L. species is currently considered an important source of compounds of high biological value such as lupeol. This is related to different and important biological activities to human health.

Objective: The objective of this study was to encapsulate the C. uvifera extract in nanofibers made with the biopolymers gelatin (G)/high-grade polymerization agave fructans (HDPAF) in the proportions 1:0, 1:1, 1:2, 1:3 and 0:1, through the electrospinning process, in addition to evaluating the antimutagenic and antiproliferative properties of the encapsulated extract.

Methods: The physicochemical characteristics of the nanofibers were evaluated, as well as the antiproliferative and antimutagenic activities of the encapsulated and unencapsulated extract. SEM evaluation shows nanofibers of smooth, continuous morphology and nanometric size (50-250 nm). The TGA, FTIR-ATR, HPLC-MS analyses reveal the presence of the extract in the nanofibers.

Results: The extract did not show a mutagenic effect during the development of the Ames test, on the other hand, the MTT test showed the antiproliferative effect at the concentrations of 50 and 100 μg/mL of extract.

Conclusion: The extract of C. uvifera loaded in nanofibers elaborated by electrospinning with the G/HDPAF biopolymers conserves its antimutagenic and antiproliferative properties.
